PURPOSE  OF  THIS  BOOK 


With  the  steady  development  of  the  use  of  fans,  heaters,  and  air 
washers  for  all  industrial  purposes,  there  has  sprung  up  a  need  for  a 
book  that  will  give  in  concise  form  the  information  required  to  properly 
select  this  apparatus  to  meet  given  requirements.  Not  an  abbreviated 
compilation  suitable  for  use  only  for  a  limited  number  of  applications, 
but  one  that  will  give  to  the  architect  or  the  engineer  information  cover- 
ing a  wide  range  of  types  and  sizes  adapted  to  every  industrial  need. 

In  the  compilation  of  this  book,  the  B.  F.  Sturtevant  Company 
have  purposely  avoided  devoting  large  space  to  theories  which  are 
probably  familiar  to  most  architects  and  engineers.  They  have  instead, 
devoted  the  book  to  actual  information  on  performances. 

The  B.  F.  Sturtevant  Company,  building  the  most  complete  line  of  fans 
and  allied  apparatus  as  well  as  the  largest  quantity,  are  in  a  position  to 
supply  this  apparatus  to  meet  any  requirements  and  in  this  book  will  be 
found  the  principal  dimensions,  capacities  and  horse  powers  over  a  wide 
range  of  service  of  their  complete  lines. 

Knowing  the  requirements,  it  is  an  easy  matter  to  select  the  type  and 
size  of  apparatus  to  fulfill  them  to  the  best  advantage,  and  also  to  find 
the  principal  dimensions  that  will  aid  in  making  the  preliminary  layout. 

A  careful  reading  of  the  explanation  of  tables  at  the  beginning  of  each 
section  will  show  clearly  the  basis  upon  which  the  tests  were  made  and 
will  aid  greatly  in  selecting  the  proper  apparatus. 

It  is  with  the  desire  to  aid  those  whose  work  it  is  to  select  and  apply 
apparatus  to  various  industrial  problems  that  the  B.  F.  Sturtevant 
Company  have  gone  to  the  great  expense  entailed  in  the  publication  of 
this  book.  If  our  friends  to  whom  this  book  is  loaned  find  it  of 
assistance,  then  its  object  is  fulfilled  and  the  expense  is  warranted.

DEFINITIONS 

Blower  or  Double  Inlet  Fan.  A  Centrifugal  Blower  is  a  cased  fan  wheel  having 
two  inlets  for  the  admission  of  air,  one  on  either  side  and  each  concentric  with  the 
shaft. 

Exhauster  or  Single  Inlet  Fan.  An  Exhauster  is  of  much  the  same  construction  as 
a  Blower,  but  has  only  one  inlet,  and  that  usually  in  the  side  farthest  from  the  pulley, 
engine,  turbine  or  motor. 

Overhung  Wheel  Fan.  An  Overhung  Wheel  Fan  is  one  where  the  wheel  is  over- 
hung upon  the  shaft,  that  is,  where  both  of  the  bearings  supporting  the  shaft  are  on 
one  side  of  the  wheel.  This  is  usually  arranged  so  that  the  pulley  runs  between  the 
two  bearings,  and  the  shaft  is  extended  through  the  fan  casing  to  take  the  wheel. 
Exhausters  are  nearly  always  of  the  Overhung  Wheel  type,  except  in  the  larger  sizes. 

Overhung  Pulley  Fan.  An  Overhung  Pulley  Fan  is  one  in  which  there  is  a  bearing 
on  either  side  of  the  fan  wheel.  The  shaft  being  extended  through  one  of  the  bearings 
to  take  the  pulley  which  is  overhung  upon  it.  Blowers  and  large  Exhausters  are 
usually  of  the  Overhung  Pulley  type. 

Discharge.  The  discharge  of  a  Blower  or  Exhauster  is  designated  by  the  direction  in 
which  the  air  is  delivered  from  the  casing;  as  for  instance,  bottom  horizonal  discharge 
or  upblast  discharge. 

Hand.  The  hand  of  a  fan  is  that  which  designates  upon  which  side  of  the  casing  the 
pulley  or  other  driving  apparatus  is  located,  when  one  is  facing  the  outlet  of  the  fan. 
A  right  hand  fan  is  one  having  the  pulley,  engine,  turbine  or  motor  on  the  right  as  one 
faces  the  outlet,  and  a  left  hand  fan  is  one  having  the  pulley,  engine,  turbine  or  motor 
on  the  left  as  one  faces  the  outlet.  An  exception  to  the  above  occurs  when  the  pulley, 
engine,  turbine  or  motor  is  placed  in  the  inlet  of  a  single  inlet  fan,  in  which  case  the 
housing  itself  may  be  left  hand,  and  yet  the  pulley,  engine,  turbine  or  motor  may  be 
on  the  right.  In  such  cases,  which  are  very  infrequent  and  usually  impracticable,  full 
explanation  should  be  given  to  avoid  confusion. 

WTith  up  or  down  angular  discharge  also  the  hand  is  determined  by  the  location  of  the 
motor,  turbine,  pulley  or  engine,  when  the  observer  stands  at  the  discharge  end  of  the 
fan. 

Full  Housing  Fans.     A  fan  with  full  housing  has  a  complete  scroll  or  casing. 

Three-quarters  and  Seven-eighths  Housing  Fans.  When  the  lower  portion  of  the 
scroll  is  dispensed  with,  and  the  fan  is  located  upon  a  foundation  which  serves  the 
purpose  of  a  lower  part  of  the  casing,  the  fan  is  called  three-quarters  housing  fan,  in 
the  Steel  Plate  type,  and  seven-eighths  housing  fan  in  the  Multivane  type. 


All  dimensions  given  in  this  book  are  for  approximate  use,  and  should  not  be  used  for 
foundation  drawings,  etc.  Blue  Prints  containing  dimensions  will  be  furnished  for

General  Explanation  of  Tables 

The  free  delivery  of  air  from  every  fan  as  actually  installed  is  un- 
avoidably retarded  by  the  frictional  resistance  of  the  surfaces  with 
which  the  moving  air  is  in  contact  and  by  changes  in  its  velocity 
and  direction  of  motion. 

In  any  system  of  conduits,  the  sum  of  all  these  resistances  is  always 
the  same  when  a  given  volume  of  air,  or  gas  at  a  given  density,  is 
flowing,  and  is  generally  called  the  "maintained  resistance"  of  the 
system.  It  is  usually  referred  to  in  terms  of  the  static  pressure  re- 
quired to  overcome  the  "maintained  resistance,"  and  is  measured  in 
inches  of  water. 

The  "maintained  resistance"  of  any  system  varies  directly  as  the 
square  of  the  volume  delivered  through  the  system  and  directly  as 
the  density  of  the  air  or  gas  handled. 

All  the  capacity  tables  in  this  book  give  the  speed  and  shaft  horse- 
power required  to  deliver  any  volume  against  any  maintained  resis- 
tance within  the  capacity  of  the  fan  referred  to. 

All  tables  unless  otherwise  stated  are  calculated  for  air  having  a 
density  of  .075  Ibs.  per  cubic  foot,  which  is  the  density  of  normal 
air  at  65°  F.  and  at  sea  level,  or  what  may  be  called  standard  air. 
The  calculations  are  based  in  all  cases  upon  the  results  of  carefully 
conducted  tests  made  in  our  testing  laboratory.  The  volumes  were 
determined  from  velocities  measured,  unless  otherwise  stated,  in  a 
pipe  the  size  of  the  fan  outlet,  by  means  of  a  pitot  tube  of  the  pin- 
hole  form.  A  sufficient  number  of  readings  of  the  velocity  head  were 
taken  at  properly  located  points  in  the  pipe  to  determine  the  average 
velocity  accurately.  The  static  pressures  were  read  from  the  static 
side  of  the  same  pitot  tube  and  averaged. 

EFFECT  OF  TEMPERATURE  AND  ALTITUDE 

The  maintained  resistance  against  which  any  fan  at  a  given  speed 
will  deliver  a  certain  volume,  varies  directly  as  the  density  of  the  air 
or  gas  handled,  and  the  shaft  horsepower  required,  also  varies 
directly  as  the  density. 

Whenever  it  is  desired  to  select  a  fan  to  handle  air  of  a  greater  or 
less  density  than  .075  Ibs.  per  cubic  foot  owing  to  a  different  temper- 
ature, or  altitude,  or  gas  of  a  composition  different  from  air,  the 
above  facts  must  be  applied  in  using  the  tables. 


Since  the  pressure  varies  directly  with  the  density  it  follows  that  the 
table  pressure  under  which  the  fan  is  to  be  chosen  for  a  given  volume 
at  a  given  speed  must  bear  the  same  ratio  to  the  required  pressure 
as  does  air  at  "normal"  density  to  the  density  of  the  air  or  gas  being 
considered.  For  instance,  if  the  density  of  the  air  to  be  used  is  .5 
that  of  standard  air,  then  the  pressure  actually  obtained  will  be  only 
.5  of  that  shown  in  the  tables.  Therefore,  the  fan  must  be  picked 
under  a  pressure  such  that  .5  of  it  will  be  the  pressure  required,  e.g., 
if  1"  is  the  desired  pressure  with  air  whose  density  is  .5  of  standard 
air,  the  fan  must  be  picked  under  the  2"  column,  then  the  actual 
pressure  will  be  1".  Usually  the  reciprocal  is  used  in  finding  the 
table  pressure,  that  is,  for  the  above,  standard  air  is  two  times 
heavier  jthan  the  air  under  consideration  and  the  table  pressure 
equals  1x2  equals  2". 

It  is  obvious  that  the  horse-power  shown  under  the  table  pressure, 
which  is,  of  course,  the  horse-power  for  air  at  .075  density,  will  be 
too  high  by  the  same  ratio  as  that  of  the  densities,  because  the 
volume  and  speed  are  the  same  and  the  density,  and  in  consequence 
the  pressure,  is  the  only  factor  that  has  changed.  Therefore,  the 
table  horse-power  must  be  multiplied  by  the  ratio  of  density  to  obtain 
the  true  horse-power.  In  the  above  example  the  actual  horse-power 
would  be  .5  of  that  shown  in  the  table  under  the  2"  pressure  column. 

When  choosing  a  fan  to  operate  at  high  efficiency,  not  only  must  a  proper  size  be  used  but  in 
addition  the  fan  must  run  at  an  efficient  speed.  As  an  aid  to  customers  we  have  placed  black 
lines  under  certain  volumes  and  horsepowers,  and  one  of  the  performances  above  the  black 
underline  in  any  particular  column  should  be  chosen.

Fan.     It  shall  be  made  ( single  or  double )   inlet,  ( single  or  double ) 

width,  (right  or  left) hand, discharge  and  have  (full  or  K) 

housing.   The  wheel  shall  be  not  less  than "  diameter.   The  outlet  shall  be  .  .  . . " 

by ",  the  diameter  of  the  inlet  shall  be ".   The  total  height  of  the  fan  housing 

shall  be ",  the  width  in  direction  of  shaft ",  and  the  length  transverse 

to   shaft ". 

The  fan  shall  have  a  capacity  of cubic  feet  per  minute  against  a  resistance  of 

"  water  gauge  either  at  the  inlet  or  at  the  outlet  (or  at  both  taking  the  sum)  and 

shall  operate  at  approximately R.P.M.,  requiring  approximately B.H.P. 

Housing.  The  housing  shall  be  of  spiral  form  constructed,  of  steel  plate  strongly 
braced,  bolted  and  riveted  to  a  rigid  frame  of  angle  irons.  The  side  plates  and  round- 
about sheet  shall  be  made  of  No.  11  gauge  for  fans  above  45"  high.  The  smaller  sizes 
shall  have  these  parts  made  of  No.  14  gauge  plate.  The  outlet  shall  be  rectangular  in 
shape  and  consist  of  angle  irons  bolted  to  the  housing  and  arranged  for  connection  to  a 
discharge  duct.  The  inlet  shall  be  of  cone  shape  and  so  constructed  as  to  allow  the 
wheel  to  be  taken  out  through  the  opening  caused  by  the  removal  of  the  cone.  In  the 
single  inlet  fan  the  side  opposite  the  inlet  shall  be  closed  by  a  dished  plate  bolted  to  the 
side  of  the  housing.  The  cutoff  piece  shall  be  made  of  a  sheet  bent  180  degrees  upon 
itself  and  having  the  two  ends  bolted  to  the  spiral  sheet,  thus  leaving  no  edges  of 
metal  which  can  in  any  way  be  acted  upon  by  the  air  issuing  from  the  outlet  so  as  to 
produce  vibration,  and  therefore,  noise  at  this  point. 

Wheel.  The  blades  of  the  wheel  shall  be  made  of  refined  steel  plate  and  spooned 
with  spherical  depressions  to  efficiently  handle  the  air.  The  blades  shall  be  pressed 
and  formed  while  hot  by  means  of  punch  and  die  to  insure  uniformity  and  strength  in 
the  blades  throughout  the  wheel.  The  hub  shall  be  made  of  cast  iron  having  cast  in- 
tegral with  it  and  emanating  from  it,  steel  arms  of  "T"  section.  The  hub  shall  be 
accurately  bored  and  fitted  with  keyway  and  set  screws.  The  blades  shall  be  riveted 
at  either  end  to  annular  steel  plate  rings  or  side  plates.  The  holes  through  which  the 
blades  are  riveted  to  the  side  plates  shall  be  punched  to  template,  as  well  as  the  blades 
themselves,  to  insure  the  proper  position  of  each  blade  in  the  wheel.  For  diameters 
above  46",  a  third  annular  ring  shall  be  placed  in  the  center  of  the  wheel,  and  two  hubs 
used  instead  of  one.  The  outer  ends  of  the  "T"  arms  emanating  from  the  hub  shall 
be  riveted  to  the  center  portion  of  the  driving  blades  which  shall  be  of  thicker  metal 
than  the  intermediate  blades.  The  wheel  shall  be  absolutely  symmetrical  either  side 
of  its  center,  and  having  no  back  plate  can  be  used  for  either  a  right  or  left  hand  fan, 
and  have  either  single  or  double  inlet.  The  wheel  shall  be  very  carefully  balanced. 

Bearings.  The  bearings  shall  be  of  the  spherical  self-aligning  ring  oiled  type  and 
bolted  to  their  support.  They  shall  be  of  large  diameter  and  built  extra  long  to  give 
ample  bearing  surface.  Each  bearing  shall  be  fitted  with  two  oil  rings  which  feed  oil 
on  to  the  shaft  from  a  large  oil  well  located  in  the  bottom  part  of  the  box.  The 
bearings  shall  be  lined  with  the  best  quality  babbit,  containing  upwards  of  85^  tin, 
bored  and  scraped  to  exact  size. 

Shaft.  The  shaft  shall  be  made  of  steel  forging  and  after  the  keyways  are  cut, 
shall  be  accurately  turned  and  ground.

MULTIVANE  FAN— DESIGN  2 

EXPLANATION  OF 
SPECIFICATION  REQUIREMENTS 

Noise.  Special  attention  is  called  to  the  construction  of  the  cut-off  point,  which, 
considering  fans  in  general,  is  the  seat  of  most  noise  in  the  nature  of  a  sustained 
metallic  note.  Obviously  any  edge  of  metal  whether  directly  or  indirectly  in  the  flow 
of  air  can  be  acted  upon  more  or  less  like  a  reed  and  the  design  of  cut-off  in  this  fan 
avoids  this  condition. 

The  flow  of  air  over  the  surfaces  in  a  fan  wheel  and  casing  obviously  produces  any 
noise  which  may  exist  ( a  fan  wheel  revolving  in  a  vacuum  will  produce  no  noise,  as- 
suming of  course,  proper  mechanical  balance  in  the  wheel ) .  The  noise  is  also  a 
function  of  the  velocity  of  flow.  In  this  fan  the  velocity  at  all  points  as  the  air  passes 
through  the  wheel  is  lower  than  in  the  general  run  of  fans  of  this  type  or  as  used  for 
this  service,  thereby  operating  against  the  production  of  noise. 

Distribution  of  Work  and  Stresses.  The  spherical  depressions  grip  the  air  and 
prevent  it  from  slipping  along  the  blade  to  the  side  of  the  wheel  opposite  the  inlet, 
thus  distributing  the  work  along  the  entire  length  of  the  blade. 

The  driving  arms  of  the  hub  being  attached  to  the  center  of  the  driving  blades,  in 
other  words  at  a  point  one-half  way  along  their  axial  length,  produce  a  construction  in 
which  the  stresses  coming  upon  it  in  operation  are  perfectly  distributed  and  balanced. 

Strength  and  Rigidity.  Not  only  is  the  driving  effort  applied  at  the  logical  and 
proper  point  but  this  has  the  added  feature  of  holding  the  wheel  in  shape  and  prevent- 
ing the  blades  from  bowing  out.  Each  blade  is  like  a  uniformly  loaded  beam  when  the 
fan  is  in  operation,  that  is,  centrifugal  force  is  acting  alike  on  each  element  of  the  blade. 
Under  high  speed  an  improperly  designed  wheel  will  first  show  signs  of  failing  in  the 
bulging  or  bowing  out  of  the  blades  at  their  center,  which  in  turn  moves  the  two  side 
plates  nearer  together.  Without  a  center  support  construction  there  is  nothing  to  stop 
the  movement  of  the  side  plates  toward  each  other  except  the  ability  of  the  blade  to 
resist  bending  (not  stretching).  With  the  center  support  construction,  however,  the 
driving  blades  are  tied  down  at  their  center  by  their  connection  to  the  driving  arms, 
thus  producing  a  strut  or  spacing  piece  at  each  point  where  the  driving  blade  is  located 
which  will  not  permit  the  side  plates  to  move  toward  each  other.  The  intermediate 
blades,  therefore,  to  bulge  or  bow  out  must  either  stretch  themselves  or  pull  the  rivets. 

Additional  Strength  in  Larger  Sizes.  In  sizes  No.  10  and  above  the  center 
annulus  carries  out  to  a  much  greater  degree  the  strengthening  feature  of  tying  the 
blades  at  the  center,  thereby  doing  away  with  any  chance  of  bowing  out.  That  is, 
every  blade  in  the  wheel  is  tied  down  at  the  center.  The  spider  arm  construction  with 
center  support  is  considerably  stronger  than  the  usual  designs  of  wheel  supported  from 
the  back. 

Wearing  Qualities.  Barring  the  metal  of  the  fan  itself  being  subjected  to  violent 
corrosion  or  chemical  action  of  gases  handled  by  the  fan  the  brunt  in  the  long  run  is 
borne  by  the  shaft  and  bearings.  Therefore,  for  long  satisfactory  service  a  shaft 
which  is  carefully  turned  and  ground  to  gauge  running  in  bearings  containing  a  very 
high  quality  babbit  metal  is  bound  to  show  its  worth.

Multivane  Fan — Design  2 

EXPLANATION  OF  TABLES 

The  capacities  in  the  following  tables  are  measured  in  a  pipe  having 
an  area  fifty  percent  greater  than  the  fan  outlet.  The  proportions 
of  these  fans  are  such  that  the  outlet  velocities  are  high  at  normal 
load.  By  expanding  from  the  outlet  to  a  fifty  percent  larger  pipe  a 
part  of  this  velocity  is  transformed  into  useful  pressure,  thereby 
increasing  the  efficiency  of  the  fan. 

In  cases  where  this  expansion  is  not  used  a  correction  should  be 
made  by  reducing  the  maintained  resistance  from  the  value  at  the 
head  of  the  tables  by  an  amount  equal  to  forty  five  percent  of  the 
velocity  head  in  the  fan  outlet. 

For  further  information  we  refer  you  to  the  general  explanation  of 
tables  at  the  front  of  the  book.

MULTIVANE  FAN— DESIGN  3 

SPECIFICATIONS 

General.     There  shall  be  furnished  a  No ,  design  No.  3,  Sturtevant  Multivane 

Fan.     It  shall  be  made  ( single  or  double )   inlet,  ( single  or  double ) 

width,  (right  or  left) hand, discharge  and  have  (full  or  %) 

housing.   The  wheel  shall  be  not  less  than "  diameter.   The  outlet  shall  be  .  .  .  . " 

by ",  the  diameter  of  the  inlet  shall  be ".   The  total  height  of  the  fan  housing 

shall  be ",  the  width  in  direction  of  shaft ",  and  the  length  transverse 

to   shaft ". 

The  fan  shall  have  a  capacity  of cubic  feet  per  minute  against  a  resistance  of 

"  water  gauge  either  at  the  inlet  or  at  the  outlet  (or  at  both  taking  the  sum)  and 

shall  operate  at  approximately R.P.M.,  requiring  approximately B.H.P. 

Housing.  The  housing  shall  be  of  spiral  form  constructed  of  steel  plate  strongly 
braced,  bolted  and  riveted  to  a  rigid  frame  of  angle  irons.  The  side  plates  and  round- 
about sheet  shall  be  made  of  No.  11  gauge  for  fans  above  45"  high.  The  smaller  sizes 
shall  have  these  parts  made  of  No.  14  gauge  plate.  The  outlet  shall  be  rectangular  in 
shape  and  consist  of  angle  irons  bolted  to  the  housing  and  arranged  for  connection  to  a 
discharge  duct.  The  inlet  shall  be  of  cone  shape  and  so  constructed  as  to  allow  the 
wheel  to  be  taken  out  through  the  opening  caused  by  the  removal  of  the  cone.  In  the 
single  inlet  fan  the  side  opposite  the  inlet  shall  be  closed  by  a  dished  plate  bolted  to  the 
side  of  the  housing.  The  cutoff  piece  shall  be  made  of  a  sheet  bent  180  degrees  upon 
itself  and  having  the  two  ends  bolted  to  the  spiral  sheet,  thus  leaving  no  edges  of 
metal  which  can  in  any  way  be  acted  upon  by  the  air  issuing  from  the  outlet  so  as  to 
produce  vibration,  and  therefore,  noise  at  this  point. 

Wheel.  The  blades  of  the  wheel  shall  be  made  of  refined  steel  plate  and  spooned 
with  spherical  depressions  to  efficiently  handle  the  air.  The  blades  shall  be  pressed 
and  formed  while  hot  by  means  of  punch  and  die  to  insure  uniformity  and  strength  in 
the  blades  throughout  the  wheel.  The  hub  shall  be  made  of  cast  iron  having  cast  in- 
tegral with  it  and  emanating  from  it,  steel  arms  of  "T"  section.  The  hub  shall  be 
accurately  bored  and  fitted  with  keyway  and  set  screws.  The  blades  shall  be  riveted 
at  either  end  to  annular  steel  plate  rings  or  side  plates.  The  holes  through  which  the 
blades  are  riveted  to  the  side  plates  shall  be  punched  to  template,  as  well  as  the  blades 
themselves,  to  insure  the  proper  position  of  each  blade  in  the  wheel.  For  diameters 
above  46",  a  third  annular  ring  shall  be  placed  in  the  center  of  the  wheel,  and  two  hubs 
used  instead  of  one.  The  outer  ends  of  the  "T"  arms  emanating  from  the  hub  shall 
be  riveted  to  the  center  portion  of  the  driving  blades  which  shall  be  of  thicker  metal 
than  the  intermediate  blades.  The  wheel  shall  be  absolutely  symmetrical  either  side 
of  its  center,  and  having  no  back  plate  can  be  used  for  either  a  right  or  left  hand  fan, 
and  have  either  single  or  double  inlet.  The  wheel  shall  be  very  carefully  balanced. 

Bearings.  The  bearings  shall  be  of  the  spherical  self-aligning  ring  oiled  type  and 
bolted  to  their  support.  They  shall  be  of  large  diameter  and  built  extra  long  to  give 
ample  bearing  surface.  Each  bearing  shall  be  fitted  with  two  oil  rings  which  feed  oil 
on  to  the  shaft  from  a  large  oil  well  located  in  the  bottom  part  of  the  box.  The 
bearings  shall  be  lined  with  the  best  quality  babbit,  containing  upwards  of  85$  tin, 
bored  and  scraped  to  exact  size. 

Shaft.  The  shaft  shall  be  made  of  steel  forging  and  after  the  keyways  are  cut, 
shall  be  accurately  turned  and  ground. 


MULTIVANE  FAN— DESIGN  3 

EXPLANATION  OF 
SPECIFICATION  REQUIREMENTS 

Noise.  Special  attention  is  called  to  the  construction  of  the  cut-off  point,  which, 
considering  fans  in  general,  is  the  seat  of  most  noise  in  the  nature  of  a  sustained 
metallic  note.  Obviously  any  edge  of  metal  whether  directly  or  indirectly  in  the  flow 
of  air  can  be  acted  upon  more  or  less  like  a  reed  and  the  design  of  cut-off  in  this  fan 
avoids  this  condition. 

The  flow  of  air  over  the  surfaces  in  a  fan  wheel  and  casing  obviously  produces  any 
noise  which  may  exist  ( a  fan  wheel  revolving  in  a  vacuum  will  produce  no  noise,  as- 
suming of  course,  proper  mechanical  balance  in  the  wheel ) .  The  noise  is  also  a 
function  of  the  velocity  of  flow.  In  this  fan  the  velocity  at  all  points  as  the  air  passes 
through  the  wheel  is  lower  than  in  the  general  run  of  fans  of  this  type  or  as  used  for 
this  service,  thereby  operating  against  the  production  of  noise. 

Distribution  of  Work  and  Stresses.  The  spherical  depressions  grip  the  air  and 
prevent  it  from  slipping  along  the  blade  to  the  side  of  the  wheel  opposite  the  inlet, 
thus  distributing  the  work  along  the  entire  length  of  the  blade. 

The  driving  arms  of  the  hub  being  attached  to  the  center  of  the  driving  blades,  in 
other  words  at  a  point  one-half  way  along  their  axial  length,  produce  a  construction  in 
which  the  stresses  coming  upon  it  in  operation  are  perfectly  distributed  and  balanced. 

Strength  and  Rigidity.  Not  only  is  the  driving  effort  applied  at  the  logical  and 
proper  point  but  this  has  the  added  feature  of  holding  the  wheel  in  shape  and  prevent- 
ing the  blades  from  bowing  out.  Each  blade  is  like  a  uniformly  loaded  beam  when  the 
fan  is  in  operation,  that  is,  centrifugal  force  is  acting  alike  on  each  element  of  the  blade. 
Under  high  speed  an  improperly  designed  wheel  will  first  show  signs  of  failing  in  the 
bulging  or  bowing  out  of  the  blades  at  their  center,  which  in  turn  moves  the  two  side 
plates  nearer  together.  Without  a  center  support  construction  there  is  nothing  to  stop 
the  movement  of  the  side  plates  toward  each  other  except  the  ability  of  the  blade  to 
resist  bending  (not  stretching) .  With  the  center  support  construction,  however,  the 
driving  blades  are  tied  down  at  their  center  by  their  connection  to  the  driving  arms, 
thus  producing  a  strut  or  spacing  piece  at  each  point  where  the  driving  blade  is  located 
which  will  not  permit  the  side  plates  to  move  toward  each  other.  The  intermediate 
blades,  therefore,  to  bulge  or  bow  out  must  either  stretch  themselves  or  pull  the  rivets. 

Additional  Strength  in  Larger  Sizes.  In  sizes  No.  10  and  above  the  center 
annulus  carries  out  to  a  much  greater  degree  the  strengthening  feature  of  tying  the 
blades  at  the  center,  thereby  doing  away  with  any  chance  of  bowing  out.  That  is, 
every  blade  in  the  wheel  is  tied  down  at  the  center.  The  spider  arm  construction  with 
center  support  is  considerably  stronger  than  the  usual  designs  of  wheel  supported  from 
the  back. 

Wearing  Qualities.  Barring  the  metal  of  the  fan  itself  being  subjected  to  violent 
corrosion  or  chemical  action  of  gases  handled  by  the  fan  the  brunt  in  the  long  run  is 
borne  by  the  shaft  and  bearings.  Therefore,  for  long  satisfactory  service  a  shaft 
which  is  carefully  turned  and  ground  to  gauge  running  in  bearings  containing  a  very 
high  quality  babbit  metal  is  bound  to  show  its  worth.

Multivane  Fan — Design  3 


EXPLANATION  OF  TABLES 

These  fans  have  very  large  outlets  compared  to  their  capacity  and 
consequently  they  have  low  outlet  velocities.  The  large  outlet  when 
connected  to  a  pipe  of  the  same  size  produces  a  chimney  efiect  which 
converts  a  large  part  of  the  velocity  in  the  casing  into  useful  pressure. 
These  fans  should  not  be  used  without  a  pipe  upon  the  outlet  be- 
cause without  the  pipe  the  conversion  effect  is  largely  lost.  Neither 
should  they  be  used  upon  a  pipe  of  less  area  than  the  outlet  of  the 
fan. 

Other  than  the  above  exception  the  general  explanation  of  tables  at 
the  front  of  this  book  applies.

angular in  shape  and  consist  of  angle  irons  bolted  to  the  housing  and  arranged  for  con- 
nection to  a  discharge  duct.  The  inlet  shall  be  of  cone  shape  and  so  constructed  as  to 
allow  the  wheel  to  be  taken  out  through  the  opening  caused  by  the  removal  of  the  cone. 
In  the  single  inlet  fan  the  side  opposite  the  inlet  shall  be  closed  by  a  dished  plate  bolted 
to  the  side  of  the  housing.  The  cutoff  piece  shall  be  made  of  a  sheet  bent  180  degrees 
upon  itself  and  having  the  two  ends  bolted  to  the  spiral  sheet,  thus  leaving  no  edges  of 
metal  which  can  in  any  way  be  acted  upon  by  the  air  issuing  from  the  outlet  so  as  to 
produce  vibration,  and  therefore,  noise  at  this  point. 

Wheel.  The  blades  of  the  wheel  shall  be  made  of  refined  steel  plate,  Both  the  outer 
or  discharge  edge  and  the  inner  or  intake  edge  of  the  blade  shall  have  a  maximum  dia- 
meter at  the  side  plates  of  the  wheel.  The  diameter  of  each  of  these  edges  shall 
diminish  as  the  center  of  the  wheel  is  approached,  at  which  point  it  is  a  minimum. 
The  outer  edge  of  the  blade  shall  not  be  in  a  plane  through  the  axis  but  shall  recede 
gradually  from  either  side  plate  in  to  the  center  of  the  wheel  while  the  inner  edge  at 
all  points  shall  lie  in  a  plane  through  the  axis  of  the  fan.  The  inner  edge  of  the  blade 
at  the  center  shall  be  relatively  of  very  small  diameter  extending  in  almost  to  the  hub 
of  the  wheel.  The  blade  shall  be  dished  and  curved  forward  in  such  a  manner  as  to 
most  efficiently  handle  the  air  from  the  time  it  enters  till  it  leaves  the  blade.  The 
blades  shall  be  pressed  and  formed  while  hot  by  means  of  punch  and  die  to  insure  uni- 
formity and  strength  in  the  blades  throughout  the  wheel.  The  hub  shall  be  made  of 
cast  iron  having  cast  integral  with  it  and  emanating  from  it,  steel  arms  of  "T"  section. 
The  hub  shall  be  accurately  bored  and  fitted  with  keyway  and  set  screws.  The  blades 
shall  be  riveted  at  either  end  to  annular  steel  plate  rings  or  side  plates.  The  holes 
through  which  the  blades  are  riveted  to  the  side  plates  shall  be  punched  to  template  as 
well  as  the  blades  themselves,  to  insure  the  proper  position  of  each  blade  in  the  wheel. 
The  outer  ends  of  the  "T"  arms  emanating  from  the  hub  shall  be  riveted  to  the  center 
portion  of  the  driving  blades  which  shall  be  of  thicker  metal  than  the  intermediate 
blades.  The  wheel  shall  be  absolutely  symmetrical  either  side  of  its  center,  and  having 
no  back  plate  can  be  used  for  either  a  right  or  left  hand  fan,  and  have  either  single  or 
double  inlet.  The  wheel  shall  be  very  carefully  balanced. 

Bearings.  The  bearings  shall  be  of  the  spherical  self-aligning  ring  oiled  type  and 
bolted  to  their  support.  They  shall  be  of  large  diameter  and  built  extra  long  to  give 
ample  bearing  surface.  Each  bearing  shall  be  fitted  with  two  oil  rings  which  feed  oil 
on  to  the  shaft  from  a  large  oil  well  located  in  the  bottom  part  of  the  box.  The 
bearings  shall  be  lined  with  the  best  quality  babbit,  containing  upwards  of  85^  tin, 
bored  and  scraped  to  exact  size. 

Shaft.  The  shaft  shall  be  made  of  steel  forging  and  after  the  key  ways  are  cut, 
shall  be  accurately  turned  and  ground. 


SUPER  VANE  FAN— DESIGN  1 

EXPLANATION  OF 
SPECIFICATION  REQUIREMENTS 

Noise.  Special  attention  is  called  to  the  construction  of  the  cut-off  point,  which, 
considering  fans  in  general,  is  the  seat  of  most  noise  in  the  nature  of  a  sustained 
metallic  note.  Obviously  any  edge  of  metal  whether  directly  or  indirectly  in  the  flow 
of  air  can  be  acted  upon  more  or  less  like  a  reed  and  the  design  of  cut-off  in  this  fan 
avoids  this  condition. 

The  flow  of  air  over  the  surfaces  in  a  fan  wheel  and  casing  obviously  produces  any 
noise  which  may  exist  ( a  fan  wheel  revolving  in  a  vacuum  will  produce  no  noise,  as- 
suming of  course,  proper  mechanical  balance  in  the  wheel ) .  The  noise  is  also  a 
function  of  the  velocity  of  flow.  In  this  fan  the  velocity  at  all  points  as  the  air  passes 
through  the  wheel  is  lower  than  in  the  general  run  of  fans  of  this  type  or  as  used  for 
this  service,  thereby  operating  against  the  production  of  noise. 

Provision  for  Minimizing  Losses.  The  greater  diameter  of  the  blade  at  each  side 
plate  does  away  with  the  loss  due  to  air  pockets,  hence  eddy  currents,  ordinarily  ex- 
isting in  this  portion  of  the  blade.  The  projection  of  the  intake  edge  of  the  blade  deep 
into  the  intake  chamber  picks  up  the  air  with  less  shock  and  delivers  it  to  the  outer  or 
major  portion  of  the  blade  where  for  the  most  part  the  work  on  the  air  is  done. 

Distribution  of  Stresses.  The  driving  arms  of  the  hub  being  attached  to  the  center 
of  the  driving  blades,  in  other  words  at  a  point  one-half  way  along  their  axial  length, 
produce  a  construction  in  which  the  stresses  coming  upon  it  in  operation  are  perfectly 
distributed  and  balanced. 

Strength  and  Rigidity.  Not  only  is  the  driving  effort  applied  at  the  logical  and 
proper  point  but  this  has  the  added  feature  of  holding  the  wheel  in  shape  and  prevent- 
ing the  blades  from  bowing  out.  Each  blade  is  like  a  uniformly  loaded  beam  when  the 
fan  is  in  operation,  that  is,  centrifugal  force  is  acting  alike  on  each  element  of  the  blade. 
Under  high  speed  an  improperly  designed  wheel  will  first  show  signs  of  failing  in  the 
bulging  or  bowing  out  of  the  blades  at  their  center,  which  in  turn  moves  the  two  side 
plates  nearer  together.  Without  a  center  support  construction  there  is  nothing  to  stop 
the  movement  of  the  side  plates  toward  each  other  except  the  ability  of  the  blade  to 
resist  bending  ( not  stretching ) .  With  the  center  support  construction,  however,  the 
driving  blades  are  tied  down  at  their  center  by  their  connection  to  the  driving  arms, 
thus  producing  a  strut  or  spacing  piece  at  each  point  where  the  driving  blade  is  located 
which  will  not  permit  the  side  plates  to  move  toward  each  other.  The  intermediate 
blades,  therefore,  to  bulge  or  bow  out  must  either  stretch  themselves  or  pull  the  rivets. 
The  spider  arm  construction  with  center  support  is  considerably  stronger  than  the 
usual  designs  of  wheel  supported  from  the  back. 

Wearing  Qualities.  Barring  the  metal  of  the  fan  itself  being  subjected  to  violent 
corrosion  or  chemical  action  of  gases  handled  by  the  fan  the  brunt  in  the  long  run  is 
borne  by  the  shaft  and  bearings.  Therefore,  for  long  satisfactory  service  a  shaft 
which  is  carefully  turned  and  ground  to  gauge  running  in  bearings  containing  a  very 
high  quality  babbit  metal  is  bound  .to  show  its  worth.

Design   i    Turbovane  Wheel. 


TURBO  VANE  FAN— DESIGN  1 

SPECIFICATIONS 

General.     There  shall  be  furnished  a  No ,  Sturtevant  Turbovane  Fan.  It  shall  be 

made  (single  or  double) ,.  inlet,  (single  or  double) width,  (right  or  left) 

hand, discharge  and  have  (full  or  %) housing.   The  wheel  shall  be 

not  less  than "  diameter, "  wide.   The  outlet  shall  be "by " ,  the 

diameter  of  the  inlet  shall  be " .  The  total  height  of  the  fan  housing  shall  be " , 

the  width  in  direction  of  shaft .  " ,  and  the  length  transverse  of  shaft " . 

The  fan  shall  have  a  capacity,  of cubic  feet  per  minute  against  a  resistance  of 

"  water  gauge  either  at  the  inlet  or  at  the  outlet  (or  at  both  taking  the  sum)  and 

shall  operate  at  approximately R.P.M.,  requiring  approximately B.H.P. 

Housing.  The  housing  shall  be  of  spiral  form  constructed  of  steel  plate  strongly  braced, 
bolted  and  riveted  to  a  rigid  frame  of  angle  irons.  The  side  plates  and  round-about 
sheet  shall  be  made  of  No.  11  gauge  plate.  The  outlet  shall  be  rectangular  in  shape  and 
consist  of  angle  irons  bolted  to  the  housing  and  arranged  for  connection  to  a  discharge 
duct.  The  inlet  shall  be  of  cone  shape  and  so  constructed  as  to  allow  the  wheel  to  be 
taken  out  through  the  opening  caused  by  the  removal  of  the  cone.  The  cutoff  piece 
shall  be  made  of  a  sheet  bent  180  degrees  upon  itself  and  having  the  two  ends  bolted 
to  the  spiral  sheet,  thus  leaving  no  edges  of  metal  which  can  in  any  way  be  acted  upon 
by  the  air  issuing  from  the  outlet  so  as  to  produce  vibration,  and  therefore,  noise  at 
this  point. 

Wheel.  The  blades  of  the  wheel  shall  be  made  of  refined  steel  plate,  The  outer  or 
discharge  edge  of  the  blade  shall  be  parallel  with  the  axis  of  the  fan.  The  inner  or 
intake  edge  shall  be  of  greatest  diameter  at  the  inlet  of  the  wheel  and  decrease  in 
diameter  as  the  back  plate  or  hub  is  approached,  thus  producing  a  blade  of  greater 
depth  at  the  back  of  the  wheel.  The  blades  shall  be  curved  with  their  convex  surface 
moving  forward  in  rotation,  and  be  of  such  shape  that  about  two  thirds  of  the  depth 
of  the  blade  from  the  outer  edge  in  toward  the  center  is  formed  in  the  curve  of  an 
involute  of  a  circle.  The  remaining  portion  shall  be  formed  in  the  arc  of  a  circle. 
The  blade  curvature  shall  be  such  as  allows  the  fan  to  handle  the  air  very  efficiently 
and  at  a  relatively  high  peripheral  speed  compared  with  the  pressure  produced.  The 
hub  shall  be  made  of  a  solid  steel  forging  riveted  to  the  driving  disc  and  accurately 
bored  and  fitted  with  keyway  and  set  screws.  The  blades  shall  be  riveted  at  the  end 
nearest  the  fan  inlet  to  an  annular  steel  plate  ring  or  side  plate,  and  at  the  end 
farthest  from  the  fan  inlet  to  a  solid  and  extra  heavy  driving  disc.  The  holes  through 
which  the  blades  are  riveted  to  the  side  plates  shall  be  punched  to  template  as  well  as 
the  blades  themselves  to  insure  the  proper  position  of  each  blade  in  the  wheel. 
Equally  spaced  along  the  axial  length  of  the  outer  or  discharge  edge  of  the  blades  shall 
be  placed  two  or  more  annular  steel  plate  rings  which  add  strength  and  rigidity  to  the 
wheel.  The  wheels  shall  be  very  carefully  balanced. 

Bearings.  The  bearings  shall  be  of  the  oil  tight,  dust  proof  pedestal  type,  and  by 
means  of  a  spherical  seat  made  self  aligning.  Each  bearing  shall  be  fitted  with  two  oil 
rings  which  feed  oil  on  to  the  shaft  from  a  large  oil  well  located  in  the  bottom  of  the 
box.  They  shall  be  of  large  diameter  and  extra  long  to  give  ample  bearing  surface. 
Each  bearing  shall  be  fitted  with  oil  throwing  collars  and  oil  baffles  also  with  a  leather 
gasket  around  the  shaft  and  at  the  outboard  end  which  absolutely  prevents  oil  getting 
out  of  the  bearing  or  dust  getting  into  it.  A  small  glass  window  shall  be  provided 
which  shows  the  supply  of  oil  in  the  bearing.  The  bearing  shall  be  very  rugged  and 
heavily  built  for  high  speed  duty,  and  lined  with  the  best  quality  babbit  containing 
upwards  of  85^  tin.  The  bearings  shall  be  carefully  bored  and  scraped  to  exact  size. 

Shaft.  The  shaft  shall  be  made  of  steel  forging  and  after  the  keyways  are  cut, 
shall  be  accurately  turned  and  ground.

TURBO  VANE  FAN -DESIGN  1 

EXPLANATION  OF 
SPECIFICATION  REQUIREMENTS 

Noise.  Special  attention  is  called  to  the  construction  of  the  cut-off  point,  which, 
considering  fans  in  general,  is  the  seat  of  most  noise  in  the  nature  of  a  sustained 
metallic  note.  Obviously,  any  edge  of  metal  whether  directly  or  indirectly  in  the  flow 
of  air  can  be  acted  upon  more  or  less  like  a  reed  and  the  design  of  cut-off  in  this  fan 
avoids  this  condition. 

The  flow  of  air  over  the  surfaces  in  a  fan  wheeLand  casing  obviously  produces  any 
noise  which  may  exist  ( a  fan  wheel  revolving  in  a  vacuum  will  produce  no  noise,  as- 
suming of  course,  proper  mechanical  balance  in  the  wheel ) .  The  noise  is  also  a 
function  of  the  velocity  of  flow.  In  this  fan  the  velocity  at  all  points  as  the  air  passes 
through  the  wheel  is  lower  than  in  the  general  run  of  fans  of  this  type  or  as  used  for 
this  service,  thereby  operating  against  the  production  of  noise. 

Provision  for  Minimizing  Losses.  The  involute  curve  of  the  blade  is  not  carried 
all  the  way  in  to  the  hub.  The  change  of  the  curve  in  near  the  hub  to  the  arc  of  a 
circle  increases  the  port  area  at  this  point  and  also  produces  a  blade  shape  which  is 
more  effective  in  starting  the  air  through  the  wheel.  By  virtue  of  the  involute  form 
of  the  major  part  of  the  blade,  the  length  of  a  normal  from  any  blade  to  the  adjacent 
blade  will  be  constant  at  all  points,  thereby  giving  equal  area  to  the  passages  through 
the  blades  and  greatly  lessening  the  losses  due  to  eddy  currents. 

Distortion.  The  heavy  annular  steel  plate  rings  closely  spaced  along  the  outer  edge 
of  the  blades  prevent  them  from  bowing  out  at  high  speed  and  also  equalize  the 
discharge  of  air  along  the  axial  length  of  the  blade. 

Strength  and  Rigidity.  The  back  plate,  inlet  side  plate,  intermediate  steel  rings, 
blades  and  hub  are  all  made  exceptionally  heavy  and  assembled  by  the  unsparing  use 
of  heavy  rivets.  This  taken  with  the  general  design  and  proportion  of  the  parts 
combines  to  produce  a  rigid  and  strong  construction. 

Wearing  Qualities.  Barring  the  metal  of  the  fan  itself  being  subjected  to  violent 
corrosion  or  chemical  action  of  gases  handled  by  the  fan  the  brunt  in  the  long  run  is 
borne  by  the  shaft  and  bearings.  Therefore,  for  long  satisfactory  service  a  shaft 
which  is  carefully  turned  and  ground  to  gauge  running  in  bearings  containing  a  very 
high  quality  babbit  metal  is  bound  to  show  its  worth.

STEEL  PLATE  FAN -DESIGN  1 

SPECIFICATIONS 

Furnish    and    erect    a    Sturtevant    steel    plate    fan,    housed;    

discharge;  hand; inlet;  overhung . ;  capable  of  deliver- 
ing  cubic  feet  of  air  per  minute  against  a  static  pressure  of inches, 

when  running  at R.  P.  M.  and  requiring  not  more  than H.  P. 

The  fan   shall  be inches  wide,  with   its   outlet inches   by    

inches  and  its  inlet inches  diameter. 

Housing.     The  fan  shall  be  constructed  with  its  housing  side  sheets  of 

gauge,  its  roundabout  or  scroll  sheet  of gauge.     The  roundabout  sheet 

shall  be  secured  to  the  scroll  angles  by  tap  bolts  of  ample  size  spaced  5  inches  on 

centers.    Scroll  angles  shall  be ......  inches  x inches  x inches. 

The  sheets  used  in  the  housing  shall  be  the  best  grade  of  blue  annealed  steel 
plate.  Housing  shall  be  substantially  braced  by  angle  iron  stiffeners  and  shall  be 
built  upon  an  angle  iron  base  of  ample  strength  to  give  the  required  rigidity. 

Wheel.     The  blast  wheel  shall  be inches  in  diameter,  of  the  side  plate 

type  containing floats  of gauge,  with  annular  side  plates  of 

gauge.    The  floats  shall  be  strongly  riveted  to  steel  T-arms inches  x 

inches  x inches,  firmly  cast  into  a  hub  spider  of  ca\st  iron. 

(In  the  smaller  size  wheels  one  spider  only  is  used  while  in  larger  wheels 
two  or  more  spiders  are  used  as  necessary.) 

The  wheel  shall  be  given  -a  careful  balance  during  and  after  assembly  to  insure 
vibrationless  operation. 

Shaft.     The  shaft  shall  be inches  in  diameter  of  best    open  hearth  steel 

turned  and  ground  to  exact  size. 

Bearings.     The  bearings  shall  be  cast  iron,  split  in  a  plane  coincident  with  the 

center  of  the  shaft,  and  lined  with  Sturtevant  White  Metal.    They  shall  be  carried 

in  chairs  so  as  to  be  self  aligning. 

Oiling  shall  be  accomplished  by  means  of  brush  oilers  sunk  in  wells  and  held 

against  the  bottom  of  the  shaft  by  spiral  springs.    This,  combined  with  capillary 

attraction,  insures  a  copious  supply  of  oil  being  supplied  at  the  right  point. 

Where  the  fans  are  to  be  used  for  the  handling  of  hot  gases,  bearings  shall  be 

furnished  containing  cored  passages  with  outlets  tapped  for  pipe  connections  so 

that  effective  water  circulation  may  be  secured. 

In  the  case  of  large  fans,  pillow  block  type  bearings  shall  be  furnished  in  place  of 

the  chair  box  type.

SPECIFICATION   REQUIREMENTS 

Wheel.  On  account  of  the  higher  periph- 
eral speeds  of  the  larger  sizes,  greater 
strength  is  necessary  than  in  the  smaller 
sizes.  For  this  reason  steel  T-arms  are  cast 
into  the  hub  rather  than  making  the  spider 
of  one  casting. 

Bearings.  The  brush  oiling  arrangement  has 
proved  itself  extremely  satisfactory  in  serv- 
ice. Ring  oil  bearings,  however,  will  be  sup- 
plied if  specified.

STEEL  PLATE  FAN— DESIGN  2 

SPECIFICATIONS 

There  shall  be  furnished  a  No Design  2,  Sturtevant  Steel  Plate  Fan. 

It  shall  be  made  (single  or  double) inlet,  (single  or  double) width, 

(right  or  left) hand, discharge,  and  three-quarter  housing.     The 

wheel  shall  be  not  less  than inches  diameter, inches  wide.    The  outlet 

shall  be inches  x inches.     The  diameter  of  the  inlet  shall  be 

inches.     The  total  height  of  the  fan  housing  shall  be inches.     The  width  in 

direction  of  the  shaft inches,  and  the  length  transverse  to  shaft inches. 

The  fan  shall  have  a  capacity  of cubic  feet  per  minute  against  a  resistance  of 

inches  water  gauge  either  at  the  inlet  or  at  the  outlet  (or  at  both  taking 

the  sum)  and  shall  operate  at  approximately R.  P.  M.  requiring  approxi- 
mately  B.  H.  P. 

Housing.  The  housing  shall  be  of  spiral  form  constructed  of  steel  plate  strongly 
braced,  bolted  and  riveted  to  a  rigid  frame  of  angle  irons.  The  outlet  shall  be  rec- 
tangular in  shape  and  shall  consist  of  angle  irons  bolted  to  the  housing  and  arranged 
for  connection  to  a  discharge  duct. 

Wheels.  The  blades  and  side  plate  of  the  wheel  shall  be  refined  steel  plate. 
The  side  plate  shall  be  reinforced  around  the  inlet,  and  periphery  with  reinforcing 
rings.  The  outer  edges  of  all  blades  shall  be  reinforced  with  angle  irons.  Both 
blades  and  side  plates  shall  be  punched  to  templates  to  insure  accuracy.  To  give 
proper  strength  the  blades  shall  be  attached  to  the  side  plates  by  means  of  angle 
irons.  Single  width  wheels  shall  have  two  spiders;  and  double  width  wheels,  four 
spiders.  The  spiders  shall  consist  of  steel  T-arms  cast  into  the  hub.  Hubs  shall 
be  accurately  bored  and  fitted  with  key  ways  and  set  screws.  The  complete  wheel 
shall  be  supported  from  two  pedestal  type  bearings  entirely  independent  of  the  fan 
housing. 

Bearings.  The  bearings  shall  be  of  rigid  type,  and  to  insure  an  ample  supply  of 
oil  to  the  surfaces,  shall  be  provided  with  three  brass  rings  and  a  carefully  grooved 
cap.  To  prevent  oil  from  escaping  from  the  ends  of  the  bearings  and  to  return  it  to 
the  reservoir,  both  upper  and  lower  boxes  shall  be  provided  with  suitable  oil 
grooves.  A  sight  oil  gauge  shall  be  located  in  the  lower  half  of  the  bearing  to  in- 
dicate the  height  of  the  oil  in  the  reservoir.  An  overflow  to  prevent  overfilling 
shall  also  be  provided.  The  bearing  shall  be  designed  with  water  passages  so  that 
cooling  water  may  be  circulated  when  necessary. 

Shaft.  The  shaft  shall  be  made  from  a  steel  forging  turned,  splined,  and  ground 
to  exact  finish.

STEEL  PLATE  FAN— DESIGN  2 

EXPLANATION  OF 
SPECIFICATION  REQUIREMENTS 

Noise.  These  fans  are  designed  primarily  for  the  slower  speeds  and  therefore 
have  comparatively  large  diameter  wheels.  This  makes  it  possible  to  ob- 
tain the  necessary  tip  speed  to  develop  the  desired  pressures  without  using 
excessive  rotative  speeds.  Also,  on  accounf  of  the  peculiar  construction  of 
the  fan  wheel,  the  air  velocities  through  the  fan  are  low  and  uniform.  This 
slow  rotative  speed,  combined  with  the  low  air  velocities,  results  in  prac- 
tically noiseless  operation  under  ordinary  conditions. 

Structural  Design.  The  satisfactory  operation  of  a  fan,  from  the  stand- 
point of  strength  and  freedom  from  distortion,  is  determined  entirely  by 
the  design  of  the  fan  wheel  and  of  the  bearings  since  the  construction  of  the 
housing  is  comparatively  simple  and  means  only  the  proper  distribution  of 
material  to  resist  the  air  pressure  within  the  casing.  In  this  fan  wheel  all 
of  the  principal  members  are  radial,  are  of  simple  design,  and  are  therefore 
best  suited  to  resist  the  stresses  tending  to  wreck  or  distort  the  fan.  The 
fan  blades  are  flat  and  are  supported  on  at  least  two  spiders  properly  lo- 
cated on  the  float  so  as  to  equalize  the  loading  on  the  float.  The  floats  are 
also  reinforced  at  the  tip  so  as  to  prevent  distortion  at  this  point. 

The  spiders  are  built  up  of  steel  T-arms  cast  into  heavy  semi-steel  hubs  and 
are  carefully  fitted  and  keyed  to  the  fan  shaft.  The  spiders  are  secured  in 
proper  position  by  steel  side  plates  on  the  sides  of  the  floats.  These  side 
plates  are  secured  to  the  floats  by  rolled  steel  angles  and  are  further  rein- 
forced by  steel  bands  at  both  the  inside  and  outside  diameters.  After  the 
wheel  has  been  assembled,  it  is  carefully  balanced  to  insure  against  vibra- 
tion when  in  operation.  Throughout  the  construction  of  this  wheel  hot 
riveting  is  used  exclusively,  thereby  insuring  the  complete  filling  of  all  holes 
and  preventing  the  movement  of  any  of  the  parts  with  respect  to  one 
another. 

The  bearings  used  in  connection  with  this  fan  are  of  heavy,  rigid,  ring-oiling 
type  and  are  mounted  on  cast-iron  pedestals  which  are  set  independently 
of  the  fan  housing.  This  insures  a  secure  bearing  for  the  fan  wheel  and 
prevents  any  vibration  which  might  be  caused  by  connection  to  the  fan 
casing.  The  bearing  pedestals  are  made  as  low  as  permissible  to  obviate 
any  possibility  of  vibration  which  is  usually  incidental  to  high  supports. 
The  bearings  are  lined  with  the  highest  grade  babbitt  bearing  metal  and  are 
scraped  to  exactly  fit  the  shaft  which  insures  perfect  operation  at  the  start 
and  makes  it  unnecessary  to  run  the  bearings  into  shape.

SPECIFICATIONS 

There  shall  be  furnished  a inch  Design  6  Steel  Plate  Plan- 
ing Mill  Exhauster.  It  shall  be  Reversible  and  Convertible 

as  to  hand  and  discharge.     The  inlet  shall  be inches  in 

diameter,  and  the  outlet inches  by inches. 

Housing.  The  housing  shall  be  made  of  steel  plate  side  sheets 
of  No.  13  gauge  secured  to  cast-iron  cone  and  inlet  side  plates 
by  tap  bolts  threaded  into  an  annular  steel  ring  which  is  riveted 
to  the  inside  of  the  steel  plate  side  sheet.

angle  by  cap  screws  spaced  five  inches  on  centers. 

Wheel.  Blast  wheel  shall  be  of  Multiblade  type  containing  18 
floats,  formed  and  curved  in  the  direction  of  rotation.  These 
floats  shall  be  placed  between  annular  side  sheets.  The  wheel 
shall  be  carried  upon  a  spider  formed  of  steel  T-arms  cast  into 

a  hub.     The  wheel  shall  be inches  in  diameter.     It  shall 

be  accurately  balanced  during  and  after  construction  to  insure 
perfect  running  balance.

STEEL  PLATE  EXHAUSTER  WITH 
MULTIBLADE  WHEEL— DESIGN  6 

EXPLANATION  OF 
SPECIFICATION  REQUIREMENTS 

Housing.  The  feature  of  this  type  is  the  ease 
with  which  it  can  be  changed  from  any  hand 
or  discharge  to  any  other  hand  or  discharge. 
This  is  done  by  removing  a  few  bolts,  turning 
the  casing  around  and  then  replacing  the 
bolts. 

* 

The  housing  is  so  shaped  as  to  give  large  capac- 
ity and  high  efficiency. 

Wheel.  The  forwardly  curved  blades  of 
the  blast  wheel  give  a  comparatively  high  pres- 
sure for  any  given  peripheral  speed  of  the 
wheel.  This  fan  is  therefore  suited  for  opera- 
tion against  high  pressures.

gin  apparatus  but  they  are  suitable  for  any  work  within  their  capa- 
cities. The  general  explanation  in  the  front  of  this  book  applies  to

STEEL  PLATE  PLANING  MILL 
EXHAUSTER— DESIGN  1 

SPECIFICATIONS 

There   shall   be   furnished   a inch,   Design    1    Sturtevant 

Steel  Plate  Planing  Mill  Exhauster  to  be hand, 

discharge,  with  pulley inches  in  diameter  by inches 

face.  The  blast  wheel  shall  be inches  in  diameter  con- 
taining floats  of gauge.  The  floats  shall  be  securely  riveted 

to  steel  T-arms  cast  into  the  hub. 

The   housing   shall   have   side   sheets   of gauge   and   a 

roundabout  sheet  of gauge.    The  roundabout  sheet  is  to 

be  secured  to  the  scroll  angle  by  tap  bolts  ^g-inch,  and  spaced 
five  inches  on  centers.  The  inlet  shall  be inches  in  diam- 
eter. The  outlets  are  cylindrical  and  are  cast  on  fans  30  to  80 
inches  inclusive  except  the  down  blast.  In  the  down  blast  fan 
the  outlet  is  part  of  the  base  casting.  In  sizes  90  to  100  inches 
fans  the  outlets  are  rectangular  and  built  of  angle  iron.  The 
cut-off  piece  shall  be  made  of  a  sheet  so  built  and  so  attached 
to  the  spiral  sheet  as  to  limit  its  vibration  and  therefore  reduce 
noise. 

Shaft.  The  shaft  shall  be  made  of  steel  forging  and  after  the

STEEL  PLATE  PLANING  MILL 
EXHAUSTER— DESIGN  1 

EXPLANATION  OF 
SPECIFICATION  REQUIREMENTS 

Wearing  Qualities.  On  account  of  the  severe 
service  to  which  Planing  Mill  Exhausters  are 
subjected,  the  casing  and  wheel  of  this  fan  are 
of  exceptionally  heavy  gauge  'so  as  to  give 
many  years  of  satisfactory  service.  Further- 
more a  great  deal  depends  upon  the  shaft  and 
bearings,  and  a  shaft  which  is  carefully  turned 
and  ground  to  gauge,  and  which  runs  in  bear- 
ings containing  a  very  high  quality  babbitt 
metal,  is  bound  to  show  its  worth.

MILL  EXHAUSTER -DESIGN  6 

SPECIFICATIONS 

Contractor    shall    furnish    one    Sturtevant    No Design    6, 

Slow  Speed  Low  Power  Exhauster.     It  shall  have  an  inlet 

inches  in  diameter,  an  outlet inches  x inches.     It  shall 

be  convertible  and  reversible  as  to  hand  and  discharge.     It  shall 

contain  a  blast  wheel inches  in  diameter,  comprising  eighteen 

floats  each  carried  on  a  steel  T-arm  cast  into  a  central  "hub,  these 
blades  to  be  tilted  forwardly  in  the  direction  of  rotation  at  their 
outer  edges.  The  blades  shall  be  connected  only  at  their  rear  or 
edges  most  remote  from  the  fan  inlet,  with  an  annular  back  plate. 
The  floats  shall  be  made  of  No gauge. 

Housing.  The  housing  shall  be  of  the  convertible  and  reversible 
type  made  up  of  steel  side  sheets  secured  to  cast-iron  inlet  and  cone 
side  plates  by  tap  bolts  threaded  into  an  annular  ring  riveted  to  the 
steel  side  sheet. 

The  roundabout  or  scroll  sheet  shall  be  secured  to  the  scroll  angles 
by  bolts  so  as  to  be  easily  replaced  if  necessary.  The  scroll  angles 
shall  be  riveted  to  the  outer  side  of  the  side  sheets.  Rivets  and  bolts 
shall  be  spaced  either  5  inches  or  2^  inches  on  centers  as  may  be 
most  desirable  for  the  work  in  question. 

Hanger.  The  hanger  shall  be  of  grey  iron  fastened  to  the  cone  side 
plate  by  tap  bolts  and  of  the  design  shown  in  the  illustration  here- 
with. It  shall  be  machined  at  the  top  to  receive  the  bearings. 

Bearings.  The  bearings  shall  consist  of  a  cast-iron  housing  which  in 
itself  forms  an  oil  reservoir  and  mounted  within  which  are  split 
sleeves  lined  with  the  best  grade  of  Sturtevant  white  metal.  These 
sleeves  shall  be  mounted  in  a  spherical  seat  so  as  to  be  self-aligning 
in  all  directions.  Oiling  shall  be  by  two  oil  rings  dipping  into  the 
reservoir.  Combination  thrust  and  oil  wiper  collars  shall  be  provided 
for  both  ends  of  each  bearing.  Bearing  housings  shall  be  recessed 
at  either  end  and  fitted  with  felt  washers.  Sight  glasses  shall  be 
inserted  in  the  bearing  housings.  The  filler  cap  shall  be  so  located 
as  to  prevent  an  excess  of  oil  being  carried  in  the  reservoir.  The 
bearing  housing  shall  be  machined  where  it  bolts  to  the  hanger  and 
shall  be  secured  thereto  by  two  bolts  of  ample  size.

SLOW  SPEED  LOW  POWER  PLANING 
MILL  EXHAUSTER— DESIGN  6 

EXPLANATION  OF 
SPECIFICATION  REQUIREMENTS 

Design  6,  Slow  Speed  Low  Power  Exhauster  is  the  most  efficient  fan 
of  its  type  on  the  market.  It  is  designed  for  very  large  capacity  and 
relatively  low  rotative  speed.  It  is  unique  in  that  it  occupies  less  space 
for  a  given  volumetric  capacity  than  any  other  fan  generally  used  for 
the  same  class  of  work. 

Housing.  The  Convertible  and  Reversible  feature  enables  the  fan 
to  be  changed  to  any  hand  or  discharge  by  removing  a  few  bolts, 
turning  the  casing  around  and  replacing  the  bolts. 

Hanger.  The  hanger  is  "low-cut"  so  that  a  large  pulley  can  be 
used  if  desired.  This  hanger  also  permits  the  use  of  a  belt  coming  up 
from  below  at  a  sharp  angle. 


599 


Slow  Speed  Low  Power  Planing  Mill 
Exhauster — Design  6 

EXPLANATION  OF  TABLES 

The  capacities  of  these  fans  are  measured  in  a  pipe  the  size  of  the 
fan  inlet  and  upon  the  inlet  side  of  the  fan,  with  outlet  also  con- 
nected to  a  pipe  of  the  same  size  by  a  taper  transformation  piece. 

The  tables  are  made  upon  this  basis  because  fans  used  for  conveying 
are  usually  piped  in  this  manner. 

Other  than  the  above  the  information  contained  in  the  general 
explanation  of  tables  shown  at  the  front  of  this  book  applies.

EXTRA  HEAVY  GAS  BLOWER— DESIGN  4 

SPECIFICATIONS 

General.     There  shall  be  furnished   a  number    Design   4   Sturtevant 

Extra  Heavy  Gas  Blower  which  shall  be  made  double  inlet,  single  width 

hand discharge  and  have  full  housing.     Blower  shall  be  supplied  with 

expanded  outlet inches  diameter  at  the  discharge  end.     Total  height  of 

fan  housing  shall  be  approximately inches;  width  of  fan  in  the  direction  of 

the  shaft  approximately inches;  length  transverse  to  the  shaft  approxi- 
mately  inches.  Blowrer  shall  have  capacity  of cubic  feet  of  free 

air  per  minute  against  resistance  of inches  water  gauge  at  the  outlet  when 

air  is  supplied  freely  to  the  inlet,  and  it  shall  operate  at  approximately 

R.  P.  M.,  requiring  approximately B.  H.  P. 

Housing.  The  housing  shall  be  of  spiral  form  constructed  of  cast  iron  and  made 
in  two  halves,  flanged  and  securely  bolted  together.  These  shall  be  split  in 
a  plane  at  right  angles  to  the  shaft.  Housing  shall  be  reinforced  by  heavy 
strengthening  ribs  running  from  the  centre  flange  to  circular  reinforcing  ribs 
concentric  with  the  inlets.  Housing  shall  be  convertible  and  drilled  so  that  the 
fan  can  be  arranged  for  in  any  one  of  the  eight  different  discharges  and  for  either 
right  or  left  hand. 

Bearings.  The  bearings  shall  be  of  the  spherical  seated  self-aligning  type  pro- 
vided with  split  bearing  sleeves  of  suitable  length  and  size  to  give  ample  bearing 
support.  Bearing  sleeves  shall  be  mounted  in  oil-tight  and  dust-tight  housing, 
and  provided  with  suitable  sight  gauge  for  determining  the  oil  level.  Bearings 
shall  be  thoroughly  and  continuously  lubricated  by  means  of  oil  rings.  Bearings 
shall  be  provided  with  thrust  collars  which  also  act  as  oil  throwers  to  catch  and 
return  to  the  oil  reservoir  any  oil  tending  to  creep  along  the  shaft.  Bearings 
shall  be  lined  with  best  quality  babbitt  metal,  containing  upwards  of  85  per  cent, 
tin,  bored,  and  scraped  to  exact  size.  Bearings  shall  be  supported  on  rigid  cast- 
iron  pedestal  which  also  supports  the  fan  housing.

CONE  FAN 

SPECIFICATIONS 

General.  There  shall  be  furnished  a  Sturtevant  Cone  Fan  of 
wheel  diameter inches. 

The  fan  shall  have  a  capacity cubic  feet  per  minute 

against  a  resistance  of inches  water  gauge  when  operating 

at  approximately R.  P.  M.,  and  requiring  approximately 

....:... B.  H.  p. 

Wheel.  The  floats  of  the  wheel  shall  be  securely  held  between 
a  back  plate  supported  by  a  cast-iron  cone  keyed  to  the  shaft, 
and  an  annular  front  plate.  The  floats  shall  be  curved  in  the 
direction  opposite  to  the  rotation  of  the  wheel. 

Shaft.  The  shaft  shall  be  made  of  a  steel  forging  and  after  the 
key  ways  are  cut  shall  be  turned  and  ground. 

Bearings.  The  bearings  shall  be  of  the  brush  oiling  type,  split 
lengthwise  along  the  center  of  the  shaft  and  supported  by  chairs 
so  as  to  be  self-aligning.  Bearings  shall  be  lined  with  the  best 
quality  babbitt,  containing  upwards  of  85  per  cent,  tin,  bored 
and  scraped  to  exact  size. 

Pulley.     The  fan  shall  be  equipped  with  a  pulley inch 

diameter,  and  with  face inches  wide.- 


CONE  FAN 

EXPLANATION  OF 
SPECIFICATION  REQUIREMENTS 

It  will  be  noted  that  the  Cone  Fan  has  no  housing,  and  is  gen- 
erally used  in  connection  with  a  plenum  chamber.  The  back- 
wardly  curved  floats  give  very  quiet  operation,  and  the  cone  fan 
is  therefore  very  desirable  where  this  is  a  factor. 


Cone  Fan 


EXPLANATION  OF  TABLES 

The  fans  of  this  type  have  no  casing  and  deliver  directly  into  a 
plenum  space  usually  of  considerable  size.  The  capacities  are  meas- 
ured from  a  pipe  discharging  from  the  room  into  which  the  fan  de- 
livers. The  maintained  resistance  is  the  static  pressure  in  the  room. 

For  further  information  refer  to  the  general  explanation  of  tables  in 
the  front  of  the  book,

Sturtevant  Turbo-Undergrate  Blower.    The  fan  wheel  shall  be 

not  less  than inches  diameter,  and  the  inside  diameter  of 

the  thimble  shall  be inches.    Blower  shall  have  a  capacity 

of cubic   feet  per  minute   against   a   resistance 

inch  water  gauge  and   shall  operate  at   approximately 

R.  P.  M.,  and  require  approximately B.  H.  P. 

Thimble.  The  thimble  shall  be  of  cast  iron  and  shall  have  the 
end  at  which  the  air  enters  curved  so  as  to  offer  no  sharp  angle 
to  the  entering  air. 

Fan  Wheel.  The  fan  wheel  shall  be  of  the  *lisc  type  of  sheet 
aluminum  blades,  riveted  to  a  bronze  hub  with  hard-drawn 
copper  rivets.  The  hub  shall  be  accurately  machined,  and  the 
wheel  shall  be  overhung  on  the  extended  turbine  shaft. 

Turbine.  The  turbine  shall  be  of  the  single  pressure  multi- 
velocity  type,  and  the  casing  shall  be  provided  with  inspection 
holes  fitted  with  removable  plugs.  The  wheel  shall  be  one  solid

Turbo -Undergrate  Blower 

EXPLANATION  OF  TABLES 

These  blowers  are  primarily  intended  to  create  a  pressure  in  the  ash 
pit  of  boilers  or  other  furnaces. 

The  capacities  are,  therefore,  measured  with  blower  discharging  into 
a  closed  plenum  space,  the  maintained  resistance  being  the  static 
pressure  in  that  space. 

For  further  information  as  to  the  basis  of  the  following  tables  see 
the  general  explanation  of  tables  at  the  front  of  this  book.

STURTEVANT  PROPELLER 

FAN 

SPECIFICATIONS 

There   shall   be   furnished   a   Sturtevant 

inch  Propeller  Fan.    The  total  length  of  the  fan  in 

the  direction  of  the  shaft  shall  be inches 

and  the  total  overall  diameter inches.     The 

fan  shall  have  a  capacity   of cubic  feet 

per  minute  and  shall  operate  at   approximately 

R.  P.  M.,  requiring  approximately 

B.H.P. 

The  thimble  shall  be  made  of  cast  iron  in  sizes 
up  to  and  including  42-inch  and  of  steel  plate  in 
larger  sizes.  There  shall  be  bolted  to  the  flange 
of  the  thimble  three  arms  to  support  the  motor 
and  the  fan  wheel,  which  latter  shall  be  overhung 
on  the  extended  motor  shaft. 

Motor  shall  be  built  to  operate  on cur- 
rent,   volts,  cycles,  

phase.

Sturtevant  Propeller  Fan 


EXPLANATION  OF  TABLES 

These  fans  are  not  usually  applied  in  connection  with  piping  systems 
because  they  are  not  efficient  where  a  large  component  of  the  press- 
ure is  static. 

Capacities  are  therefore  measured  with  fan  discharging  into  a 
plenum  space,  the  maintained  resistance  being  the  static  pressure  in 
that  space.

STURTEV ANT  -  BLACKM AN 
PROPELLER  FAN 

SPECIFICATIONS 

We  recommend  the  use  of  the  specifications,  on 
Sturtevant  Propeller  Fans  given  on  page  808. 
Propeller  Fans  of  the  Blackman  type  are  built  by 
this  company  only  when  ordered  or  to  meet  speci- 
fications. The  demand  for  them,  however,  is 
decreasing  since  they  are  less  efficient,  of  smaller 
volumetric  capacity,  and  make  more  noise  than 
Sturtevant  Propeller  Fans.  For  these  reasons  we 
strongly  advise  the  use  of  the  latter  type. 


Sturtevant  -  Blackman  Propeller  Fan 


EXPLANATION  OF  TABLES 

These  fans  are  not  usually  applied  in  connection  with  piping  systems 
because  they  are  not  efficient  where  a  large  component  of  the  press- 
ure is  static. 

Capacities  are  therefore  measured  with  fan  discharging  into  a 
plenum  space,  the  maintained  resistance  being  the  static  pressure  in 
that  space.

SPECIFICATIONS 

See  specifications  on  page  808.  Sturtevant 
Propeller  Fans  of  the  Davidson  type  are  less 
efficient  and  more  noisy  than  the  standard 
Sturtevant  Propeller  Fan  described  on  pages 
805-821,  and  the  demand  for  the  Davidson 
type  has  therefore  decreased.  On  special 
order  or  to  meet  specifications  Sturtevant- 
Davidson  Propeller  Fans  will  be  furnished, 
but  the  other  type  is  recommended. 


844 


S turte van  t- Davidson  Propeller  Fan 


EXPLANATION  OF  TABLES 

These  fans  are  not  usually  applied  in  connection  with  piping  systems 
because  they  are  not  efficient  where  a  large  component  of  the  press- 
ure is  static. 

Capacities  are  therefore  measured  with  fan  discharging  into  a 
plenum  space,  the  maintained  resistance  being  the  static  pressure  in 
that  space.

STURTEVANT  TRACTRIX 

FAN 

SPECIFICATIONS 

There  shall  be  furnished  a  Sturtevant   No. 

Tractrix  Fan,  the  total  length  in  the 

direction  of  the  shaft  being inches,  and 

the  total  overall  diameter inches. 

The  fan  shall  have  a  capacity  of cubic 

feet  per  minute  and  shall  operate  at  approxi- 
mately  R.P.M.  requiring  approximately 

B.H.P. 

The  electric  motor  shall  be  built  to  operate 

on current, volts, cycles, 

phase. 


Tractrix  Fan 


EXPLANATION  OF  TABLES 

These  fans  are  not  usually  applied  in  connection  with  piping  systems 
because  they  are  not  efficient  where  a  large  component  of  the  press- 
ure is  static. 

Capacities  are  therefore  measured  with  fan  discharging  into  a 
plenum  space,  the  maintained  resistance  being  the  static  pressure  in 
that  space.

Sturtevant  Disc  Fan — Design  1 


EXPLANATION  OF  TABLES 

These  fans  are  not  usually  applied  in  connection  with  piping  systems 
because  they  are  not  efficient  where  a  large  component  of  the  press- 
ure is  static. 

Capacities  are  therefore  measured  with  fan  discharging  into  a 
plenum  space,  the  maintained  resistance  being  the  static  pressure  in 
that  space.

DISC  FAN  — DESIGN  2 

SPECIFICATIONS 

There   shall   be  furnished   a   Sturtevant 

Design  2  Disc  Fan  having  a  capacity  of 

cubic   feet    per   minute    against    a    resistance    of 

inches  water  gauge   and   shall   operate   at 

approximately R.  P.  M.,  requiring  ap- 
proximately  B.  H.  P. 

The  wheel  shall  have  12  floats,  firmly  riveted  to 
the  hub.  To  give  additional  strength,  sizes  42-inch 
and  larger  shall  have  each  float  braced  with  sup- 
ports extending  from  a  special  ring  on  the  hub  to 
a  point  near  the  outer  end  of  the  float. 

The  casing  shall  consist  of  steel  plate  of 

gauge  suitably  supported  with  angle  irons  on  both 
inlet  and  outlet  sides.  Removable  feet  shall  be 
bolted  to  the  fan  casing.

Sturtevant  Disc  Fan — Design  2 


EXPLANATION  OF  TABLES 

These  fans  are  not  usually  applied  in  connection  with  piping  systems 
because  they  are  not  efficient  where  a  large  component  of  the  press- 
ure is  static. 

Capacities  are  therefore  measured  with  fan  discharging  into  a 
plenum  space,  the  maintained  resistance  being  the  static  pressure  in 
that  space.

i.     All  sections  contain  four  rows. 

2.     The  overall  height  of  a  heater  above  the  bottom  of  the  base  is  determined  by  adding  to  the  nominal  height  of  pipes  one  of 
the  following  constants: 

For  sizes  Nos.  12,  15  and  18  add  8%  inches.                             For  sizes  Nos.  22,  25  and  28  add  9?s  inches. 
For  sizes  Nos.  31  and  36  add  gj-g  inches.                                  For  size  No.  40  add  ioj^  inches. 

This  additional  height  is  due  to  the  space  occupied  by  the  bate  and  by  the  elbow  at  the  top. 
\ 
Note:  —  Free  Area  is  approximately  9%  of  heating  surface.     The  percentage  varies  slightly  for  every  heater.

bottom  of  the  spray  chamber  and  fitted  with  vertical  risers  so  placed  as  to  bring 
the  spray  nozzles,  secured  to  the  risers,  in  a  plane  parallel  to  and  at  a  distance 
of  48"  in  front  of  the  eliminators.  The  upper  ends'  of  the  risers  shall  be  capped 
with  a  special  cap  that  will  permit  fastening  to  a  galvanized  angle  iron  across 
the  top  of  the  spray  chamber,  thus  holding  the  risers  securely  in  line.  There 
shall  be  not  less  than  one  atomizing  nozzle  for  each  400  cubic  feet  of  air  washed 
per  minute.  The  nozzles  shall  be  constructed  entirely  of  bronze  and  shall  have 
large  water  ways  to  prevent  clogging  of  the  nozzles  by  sediment  carried  in  the 
water.  The  nozzle  openings  shall  be  not  less  than  3-16"  in  diameter,  and  shall 
discharge  not  more  than  1^  gals,  per  minute  with  19  pounds  pressure  per  square  inch.

STURTEVANT  AIR  WASHER— TYPE  "H" 

EXPLANATION  OF 
SPECIFICATION  REQUIREMENTS 

Length  of  Washer.  For  the  most  efficient  humidifying  and  cooling  service,  an 
air  washer  must  be  so  designed  that  the  air  and  water  will  be  in  intimate  contact  for 
a  considerable  period  of  time.  To  accomplish  this,  in  the  Sturtevant  Type  "H"  Air 
Washer,  the  spray  chamber  is  over  five  feet  long.  The  nozzles  are  over  four  feet 
from  the  eliminators  and  the  total  length  of  the  washer  is  seven  feet. 

Tank.  The  tank  of  the  Sturtevant  Washer  is  constructed  of  No.  14  gauge  metal, 
which  is  heavier  than  the  tanks  of  the  washers  manufactured  by  most  companies. 
Experience  has  proved  that  the  tank  should  be  constructed  in  an  exceptionally  rigid 
manner  as  it  is  usually  required  to  contain  several  thousand  pounds  of  water  and  in 
addition  to  support  the  chamber  of  the  spray  casing. 

Trap.  The  running  trap  inserted  in  the  overflow  of  the  Sturtevant  Air  Washer  tank 
completely  eliminates  any  possibility  of  the  fan  sucking  odors  and  gases  from  the 
drain  pipe. 

Inspection  Door.  The  cast-iron  door  with  glass  panels  fitted  to  the  casing,  is  of 
ample  size  to  permit  easy  access  to  the  spray  chamber.  The  rigid  form  prevents  warp- 
ing and  eliminates  the  cracking  of  the  glass.  The  heavy  hinges  assure  that  breakage 
will  not  occur  from  slamming  of  the  door  or  from  abuse. 

Eliminators.  The  projecting  lips  of  the  horizontal  lip  perforated  baffles  or  elimin- 
ators cut  the  air  into  many  streams  bringing  all  the  air  into  contact  with  the  wet 
surfaces  upon  which  the  dirt  in  the  air  is  deposited.  The  open  construction  of  these 
baffle  plates  causes  them  to  be  continually  washed  clean  and  drained. 

Spray  Device.  The  spray  device  of  the  Sturtevant  Type  "H"  Washer  consists  of 
not  less  than  one  nozzle  for  every  400  cubic  feet  of  air  washed  per  minute.  This 
guarantees  that  the  spray  chamber  is  filled  with  a  uniform  dense  spray  and  assures 
the  thorough  wetting  of  the  air.  The  washing  of  the  eliminators  by  supplementary 
nozzles  makes  certain  that  the  surfaces  will  be  continually  wet  to  cause  the  adherance 
of  the  dust  particles. 

Pump.  The  recirculating  pump  is  of  the  double  suction  enclosed  impeller  type.  It 
is  bronze  fitted  throughout  to  give  the  maximum  service  and  wear.  The  split  casing 
permits  the  removal  of  bearings,  shaft  or  impeller  without  disturbing  the  water  con- 
nection. These  pumps  are  especially  rigid  and  assure  permanent  alignment  and  proper 
operation. 

Lighting  Fixture.  The  water  proof  marine  type  electric  fixture  insures  that  the 
interior  of  the  washer  is  properly  lighted  at  all  times  making  the  inspection  easy 
and  thorough.

be feet inches.     The  washer  shall  be  4'  0"  long  in  the  direction  of  the 

flow  of  air.     The  air  washer  shall  have  a  capacity  of cubic  feet  of  air  per  minute 

at  a  velocity  of feet  per  minute. 

Tank.  The  tank  shall  be  constructed  of  galvanized  steel  firmly  braced  to  a  rigid 
frame  of  galvanized  angle  iron.  The  plates  of  the  tank  shall  be  of  No.  14  guage;  the 
angles  shall  be  \'%"  x  1  yj' x  3-16"  and  shall  be  spaced  not  more  than  three  feet  apart. 
The  top  framing  angles  are  to  be  punched  5"  on  centers  for  3-8"  bolts  to  secure  the 
spray  chamber  casing  to  the  tank.  All  rivet  heads  and  seams  shall  be  soldered  over 
to  make  the  tank  water  tight.  The  tank  shall  be  fitted  with  a  conical  shaped  over- 
flow and  trap  to  carry  away  surplus  water.  The  trap  shall  be  provided  to  prevent 
the  admission  of  sewer  gas  from  the  drain  pipe  to  the  spray  chamber. 

Casing.  The  casing  of  the  washer  shall  be  made  of  galvanized  steel  of  No.  18  guage, 
and  thoroughly  braced  with  1 J^"  x  1  Y^'  x  3-16"  galvanized  angles,  spaced  not  more

from  the  air  after  it  has  passed  through  the  spray  chamber.  The  eliminators  shall  be  of 
the  horizontal  cut-lip  type,  arranged  in  tiers  of  not  more  than  five  foot  widths.  The 
plates  shall  not  be  lighter  than  No.  22  gauge  steel  and  they  shall  be  galvanized  after 
the  plates  have  been  cut  and  formed  to  shape.  It  shall  be  arranged  so  that  a  large 
part  of  the  surface  of  the  plates  shall  act  as  a  washing  surface  for  the  removal  of  dust 
that  impinges  upon  the  plates.  The  eliminators  shall  consist  of  one  group  in  the 
direction  of  the  flow  of  air. 

Spray  Device.  The  spray  device  shall  consist  of  a  loop  formed  of  two  pipes  into 
which  are  secured  the  spray  nozzles.  This  loop  shall  be  connected  at  both  ends  to  the 
discharge  line  from  the  recirculating  pump.  One  row  of  spray  nozzles  shall  be 
arranged  te  direct  the  spray  on  to  the  eliminators  for  the  purpose  of  washing  to  the 
tank  any  dirt  adhering  to  the  plates.-  The  nozzles  shall  be  of  brass  or  bronze  com- 
position and  shall  have  not  less  than  a  3-16"  orifice.  The  spacing  of  the  nozzles  shall 
not  be  more  than  6"  center  to  center.  The  orifice  of  the  nozzle  shall  be  unobstructed, 
except  for  an  overhanging  deflector  for  breaking  the  water  into  fine  spray.  Each 
nozzle  shall  discharge  approximately  3  gallons  of  water  per  minute  with  12  pounds 
pressure. 

Strainer.  A  double  cylindrical  brass  strainer  shall  be  fitted  to  the  tank  to  prevent 
matter  Gable  to  clog  the  water  passages  entering  the  system.  The  screens  shall  consist 
of  perforated  brass  sheets  with  the  perforations  of  the  outer  sheet  1-10"  diameter  and 
those  of  the  inner  1-16"  diameter,  The  screens  shall  be  riveted  to  frames  of  non-
